Builder Bryan Baeumler convinces his wife Sarah to uproot their growing family and head to the country where he plans to build their dream home. Bryan begins renovation on the new house while his family – including their newborn daughter – live there.

Bryan is forced to leave town, and the timing couldn't be worse as Mother Baeumler is left to battle with Mother Nature on her own. Then, Bryan returns home to a damp disaster.

As winter looms, Bryan makes major repairs to the existing part of the house and disrupts the sleeping arrangements for the entire family. Then, Sarah and Bryan's arguments get heated as they butt heads over design features in the great room and kitchen.

Bryan pushes to complete the drywall, but electrical and staircase hiccups force him to slow down. As the long winter continues, Bryan comes home to some unfortunate surprises after the family's vacation.

With spring on the way, Bryan must fix the stained limestone on the exterior of the house and fulfill Sarah's request to resurrect the old doors for the playroom. Then, the new addition is ready for hardwood, but Bryan might not be ready for the bill.

The main floor tiles finally arrive for installation, but Bryan's electrician makes a costly error. Then, Sarah goes rogue with a design feature when Bryan leaves for a trip.

The crew makes the final push to complete the addition, and Sarah must pick new lights at the eleventh hour. Then, the Baeumlers reveal their living spaces in the finished addition.

With the addition complete, Bryan is itching to keep the renovation momentum going. Meanwhile, Sarah and Bryan try to nail down the layout in the old part of the house, and Bryan pushes to vault the ceiling.

Sarah holds up work on the powder room as she makes additional, last-minute design choices. Then, the Baeumlers break down the final wall between the old and new house, and Bryan's frustration grows when Sarah asks to change the planter box in the yard.
